There are contradictions in the RFC:

Compression also has some problems.

Section 2.1 ("Confidentiality via Encryption") states that OpenPGP encrypted
messages are usually compressed.

Section 2.3 ("Compression") states that implementations MAY compress a message
after applying a signature.

Section 9.3 ("Compression Algorithms") states that an implementation MUST
support the type 0 (uncompressed data) algorithm and SHOULD support ZIP.

It seems like this wording could lead to sever interoperability problems.
